which other procedures will you suggestto study newton first law of motion in laboratory?
Answers
Answer:
Newton's First Law says that objects at rest remain at rest and objects in motion remain in motion at a constant velocity, unless acted upon by an unbalanced force. What does this mean? Well, the natural state of an object is to move at a constant velocity. We have this picture of objects that says they come to rest on their own, like a shopping cart being pushed and released. After a while, it will stop. But if there are no forces acting on an object, it will, in fact, keep going at a constant velocity.
So, for example, if you go into space and move a long way away from any planets, and then you throw a baseball, once it leaves your hand, it will keep going, basically forever. The only reason the shopping cart stops is because an unbalanced force, friction, stops it.
